Password Protection

2. Not Coded

Having a Javascript test a password where the password to test against is not coded in the Javascript might sound impossible but it can be done by making the password part of the filename of the page that is to be password protected. An example of a Javascript that does this follows:

Of course you should make this an external Javascript to make it slightly more difficult to access the source. All that you need to do then to make a password protected link is to create the page to be password protected and save it in a file with the same name as the password (with .html added to the end) and to create a link to that page (or pages) that looks like this:

Of course you may still want to use frames to help hide the relationship between the password and the page address.

When the link is selected a prompt box asking to have the password entered is displayed. If the prompt box is closed or cancel is selected then the prompt box will disappear and your visitor will remain on the current page. If a wrong password is entered then the default "page not found" page will be displayed.

Of course using this method doesn't stop someone who has figured out the actual address of the "protected" page from accessing it directly. To protect against that using Javascript we need to encrypt the password into the page itself.
